Therefore, we need to re-define the controllable dimensions for real-world interactive modulation.
In this paper, we propose to adopt the general noise (Gnoise) and general blur (Gblur) as the two controllable dimensions, as users usually focus on the visual effects brought by those two factors.
Specifically, general noise includes Gaussian noise, Poisson noise, and JPEG compression, as they all introduce unpleasant “artifacts” into images.
Note that we classify JPEG compression artifacts as Gnoise, as the JPEG blocking artifacts are visually more like noise.
The general blur includes Gaussian filter (isotropic/anisotropic), 2D sinc filter [1]}, and random resize operation, as they all weaken image details.
